BOWL ASSEMBLY.

Application filed. Februpry 1 1, 1924. Serial in. 692,028.

To all whom it may concern:

Be it known-that I, CU'RT F. ZIMANSKY, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented a new and-useful Improvement in a Bowl Assem blgkof which the following is a specification. y invention relates to improvements in well pump construction andparticularly to the construction and the assembling means for the housing members of such pumps.

The primary object of my invention is to provide an improved construction for well pumps which will simplify the manufacture and faoilitate"the assembly of the. pump.

' A further object is to provide an improved construction which will occupy a minimum area within a well casing and thus permit the use of a pump of maximum diameter within a well casing of state slze. A further object is to provide an improved means for assembling the housing members of a position.

Another object is to provide an improved assembling means adapted to hold the several housing members in accurate alignment. I accomplish these and other objects by means of the device disclosed in the drawings forming a part of the. present specification wherein like characters of reference are used to designate similar parts throughout said specification and drawings and in which,

Figs. 1 and 1 are broken vertical sections of a well. casing showing in elevation my improved pump construction as mounted therein.

Fig. 2 is a vertical section of the pump disclosing. my improved construction, and assembling means.

Referring to the drawings the numeral 1 is used to designate in general a well casing within which is mounted a rotary well pump designated in general by the numeral The pump 2 is carried by the usual discharge casing 3and is provided witha drive shaft 4 extending u wardly to the top of m the well to receive a drive pulley 6 by which the pump is operated in the well known manner.

In well pump construction of the rotary pump in rigid superimposed type, one or more runners or. impellers 7 are mounted upon the drive shaft 4 within what are'commonly termed the bowls of. the pump; said bowls being formed by a plurality of housing members assembled in superimposed position. This is commonly accomplished by flanging each housing member and connecting the members by means of bolts or threads engaging the adjacent flanges of adjacent members. The flangesmust of necessity extend outwardly from the housing members sufliciently far to accommodate the securing bolts and the actual size of the pumping mechanism designed for any stated size of well casing must accordingly be reduced and much of the effective area of the well thus be lost. A further objection to this means of assembling the housing members is that the securing of the several bolts and nuts upon the flanges requires an accurate positioning of the holes in each flange, and the securing of the bolts is a relatively long and tedious operation. My present invention is therefore directed to an improved construction which will overcomethese and other objectionable features and materially simplify the construction and assembly of the pump, which construction is shown in detail in Fig. 2 of the drawings. I

The upper and lower housing members 8 and 9 are provided with annular shoulders 11 and 12' respectively, and one or more intermediate members 13 machined to align with the upper and lower housing members and form close contact with the adjacent surfaces of adjacent housing members, only one member 13 being shown in the figure, in order to simplify'the drawin A casing 14 provided with an" inwardly disposed annular flange 16 formed at one end thereof is mounted over'thehousing members, .said casing 14 being preferably arranged to engage the outer surface of each member and retain the several members in accurate alignment. The flange 16 is arranged to engage the shoulder formed upon one of the housing members and the casing is designed to extend slightly beyond the shoulder formed upon the housing member most remote fromthe flange. Thus in the drawings, the flange 16 is arranged in en gagement with the shoulder 11 formed upon the u per housing member and the casing cxten s slightly past the shoulder 12 formed upon the lowermost housing member.

The casing 14 is provided with an internally threaded portion 17 at the end op )0- site the flange 16, said threaded portion eing arranged to receive a ring 18 threaded thereinto in such manner that the inner edge of the ring will engage the shoulder 12 of the lower housing member 9.

In assembling the pump the casing 14 is fitted over the housing members which are mounted in superimposed relation upon the shaft 4 to enclose the runners 7. The ring 18, applied over the lower end of the lower housing member 9, is then caused to engage the threads at the lower end of the casing and advanced until the inner edge of the ring engages the shoulder 12 as above described. As the ring is further advanced pressure will be applied upon the shoulders 11, 12 which will tend to draw the upper and lower housing members together and thus compress the intermediate member 13 therebetween, a moderate tightening of the ring 18 against the shoulder 12 serving to.

compress the several members into rigid contacting relation, all the members being thus secured in accurately aligned superimposed position by the single operation. Loosening of the ring is prevented by means of a set screw 19 carried by the ring and arranged to engage the adjacent housing member, a locknut 21 being preferably applied to further guard against loosening of the ring by vibration when the pump is in operation.

In constructing the housing members, the usual flanges are dispensed with and the drilling of holes to receive securing bolts entirely eliminated, the cost of manufacturing the housing members being thus materially reduced. The ring 18 is readily made by turning down and threading a piece of standard tubing of the desired size. In similar manner the casing member 14 may most readily be made by turning out the interior of similar piece of standard tubing to form the inwardly disposed flange 16, the opposite end a being thereafter internally threaded to receive the ring 18.

The housing connection above described occupies but very little space. only the thickness of a piece of standard tubing being added to the diameter of the pump. For this reason the runners and housing members may be made larger and a more effective pump be thus applied in a well casing of stated diameter, only suflicient clearance being necessary to admit a lubricating conduit 22 and to allow for slight irregularities in the well. A uniform pressure is applied at all points upon the housing members twhich members will be held in rigid connec- Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. In a'well pump, the combination with a plurality of housing members arranged to be mounted in superimposed position, of shoulders formed upon the upper and lower members; a casing engaging one of said shoulders and extending past the other shoulder; and means engaging said casing and the said other shoulder for compressing allof the housing members into rigid operative position.

2. In a well pump, the combination with a plurality of housing members arranged to be mounted in superimposed position, of shoulders formed upon the upper and lower members; a casing engaging the members and arranged to retain the same in alignment; and means carried by the casing for compressing the members into rigid operative relation.

3. In a well pump, the combination with a plurality of housing members arranged to be mounted in superimposed position, of shoulders formed upon the upper and lower members; a casing engaging the members and arranged to retain the same in alignment; an annular flange formed upon one end of the casing to engage one of the shoulders; and means connected with the other end of the casing and engaging the other shoulder for compressing all the members into rigid relation against the annular flange.

4. In a well pump, the combination with a plurality of housing members arranged to be mounted in superimposed position, of shoulders formed upon the upper and lower members; a casing engaging the members and arranged to retain the same in alignment: an inwardlv disposed annular flange upon one end of the casing and arranged to engage one of the shoulders; and a. ring mounted upon the other end of the casing and arranged to engage the other shoulder, said ring being movable relative to the casing to compress the members into rigid operative relation against the annular flange.

5. In a well pump, the combination with a plurality of housing members arranged to be mounted in superimposed relation, of shoulders formed upon the upper and lower members; a casing mounted in engagement with the members; an inwardly disposed annular flange formed upon one end of the casing and arranged to engage one of the shoulders: a ring threaded into the other end of the casing and arranged to engage the other shoulder. said ring being arranged to be advanced by its threaded connection to compress the members into rigid operative relation against the annular flange.

6. In a well pump, the combination with a plurality of housing members arranged to i shoulders; a ring threa be mounted in superimposed relation, of shoulders formed the other shoulder, said ring being arranged to be advanced by its threaded connection 10 to compress the members into rigidly operative relation against the annular flan e; and means for securing said ring in a vanced position.

In witness whereof I hereunto set my sig- 1 nature.
